I cut some floor panels for a dive barge today.
Some of the panels were almost the entire cutting area of the langmuir pro.
And the z-axis compensated fairly well with the diamond plate uneven surface height
1/4 inch aluminum diamond plate.
I was running a Hypertherm PowerMax 85 set at 65 amps.
Here are the parameters I used.
I was pretty apprehensive because this material is expensive but I ran the most complex nest dry a couple times and made sure everything was cleaned and oiled before I got going.
I ended up being very happy with the way it came out.
Less than the 16th out on the measurements in those larger panels
